Private Cloud là gì?

A private cloud refers to a cloud computing environment exclusively reserved for a single organization. Similar to any cloud infrastructure, it offers underlying compute resources such as CPU and storage that can be provisioned on demand via a self-service portal. However, in a private cloud, all resources are isolated and under the sole control of the organization. Therefore, it is often referred to as the internal or corporate cloud.

Pros and Cons of a Private Cloud?

While Public Cloud is "multi-tenancy”, a private cloud is single-tenant. Some organizations view a private cloud as providing benefits such as heightened security, flexibility, and control. They value the autonomy to shape their architectural decisions and select hardware and software that align with their specific needs. Others believe that a private cloud is necessary to meet regulatory compliance mandates for safeguarding sensitive data. However, it's essential to recognize that the benefits offered by a private cloud infrastructure are contingent upon its implementation approach.

With the above pros and cons, particularly since the issuance of Decree 13/2023/ND-CP, private cloud is an ideal solution for businesses with strict security and compliance requirements, or needing to handle sensitive data such as:

BFSI organizations.
Healthcare service providers.
Technology companies.
Medium to large-scale enterprises.
Government authorities.

Although deploying and maintaining a private cloud infrastructure requires a significant amount of initial investment capital as well as a specialized workforce to manage and maintain, it cannot be denied that many large enterprises still prioritize using this model. The main reason behind this decision is often due to the high security and privacy that the Private Cloud platform brings. This provides peace of mind regarding the protection of important information and keeps data from leaking or being accessed unlawfully from outside.

How does a Private Cloud work?

Private cloud architecture closely resembles that of the public cloud and relies on similar technological implementations:

1. Virtualization

Virtualization abstracts IT resources from their physical hardware, allowing users to create and interact with virtual machines or software units in the same manner as physical machines. Virtualization software consolidates hardware resources such as CPU, memory, and storage and dynamically allocates them to virtual machines based on demand.

2. Management software

Administrators utilize management software to centrally control and oversee their IT infrastructure as software units. This software facilitates consistent configurations across servers and application environments, ensures compliance with security standards, and optimizes resource allocation.

3. Automation technologies

Automation streamlines tasks like integrations and server provisioning, reducing the potential for errors associated with manual processes. Organizations implementing a private cloud environment must incorporate automation capabilities to enhance the efficiency of cloud infrastructure management.

Additionally, organizations must adapt their development and deployment practices to align with private cloud technologies. Practices such as DevOps and DevSecOps, centered around cloud-native applications, along with architectural approaches like microservices and containers, contribute to increased efficiency and flexibility within the private cloud environment.

Types of Private Cloud

There are 4 main types of private cloud infrastructure: on-premises private cloud, virtual private cloud (VPC), hosted private cloud, and managed private cloud.

1. On-premises private cloud

An on-premises private cloud is deployed using your organization's own resources within an internal data center. This entails purchasing, maintaining, and upgrading the necessary infrastructure, as well as ensuring its security. Managing an on-premises private cloud is costly, involving significant initial investment and ongoing expenses.

2. Virtual private cloud (VPC)

3. Hosted private cloud

Hosted Private Cloud is a type of private cloud that is hosted off-premise rather than on the customer's premises. In this cloud computing model, the cloud servers are not physically configured and installed at the customer's physical location. Instead, third-party vendors host and manage services on remote cloud servers. It offers dedicated services and applications accessible to a single organization, with lower infrastructure costs compared to other private cloud models, as it operates within the public cloud.

4. Managed private cloud

A managed private cloud is a single-tenant environment completely managed by a third party. This means that a third-party organization purchases and maintains the IT infrastructure for your organization within its data center. They handle maintenance, upgrades, support, and remote management of your private cloud resources. While managed private clouds come with a higher cost, they offer greater convenience compared to on-premises solutions.

Migration from VMware to VNG Cloud

VNG Cloud offers many cloud models designed for your specific needs, whether it is a dedicated and isolated environment where your organization can host applications, store data, and run VMware workloads with enhanced security and control.

Here, you can keep managing your existing environments with tools similar to VMware while modernizing your applications with VNG Cloud's native services. Moreover, our private cloud offers greater scalability and stronger security compared to traditional VMware environments.

With the seamless transition from traditional on-premises VMware environments to the advanced cloud infrastructures, VNG Cloud empowers businesses to optimize their operations, comply with industry data regulations, and unlock new opportunities for growth in the digital landscape.
